New York, June 19 : Lawyers Boris Epshteyn and Jenna Ellis and former U.S. Senate candidate James Lamon have pleaded not guilty to nine felony charges for their roles in trying to overturn former President Donald Trump’s Arizona election loss to Joe Biden.

The hearing Tuesday in a Phoenix courtroom marked the last of 18 arraignments in the fake elector case. 

Fifteen other people, including former New York City Mayor Rudy Giuliani and former Trump Chief of Staff Mark Meadows, pleaded not guilty to the charges.

Epshteyn, a Trump adviser, is accused of assisting Giuliani in carrying out the scheme to submit fake electors for Trump in Arizona and obstruct the certification of election results by Congress on Jan. 6, 2021. 

Prosecutors in Michigan, Nevada, Georgia and Wisconsin have also filed criminal charges related to the fake electors scheme.
